OBDII
 

I used to have a problem with my "Service Engine Soon" light coming on all the time, i checked it out, it was the eecr valve or something like that...i kept clearing the codes, and one day it just never came back on. I took it to the dealer, and they didnt see anything wrong...so i found other things to complain about once i gave up on that, and got a keychain.. Anyone else have similar occurences on the dissapearing problem codes?

The gas cap, if its not on tight enough will throw a code...Ive also noticed if the dipstick isnt all the way in(down to the o ring) the light will come on then too. Just a couple Ive noticed.

Air filter too if you don't clamp all or don't properly attach all pieces the Light comes on too.

That would just be the sensor...not the air box.
